also twice reared single examples from collected flower-heads of 
this plant. 
G. subocellana, Donoy., = Campoliliana, W. V.—Widely dis- 
tributed throughout, and generally common among sallows. The 
imago appears in May and June, and specimens are also to be 
occasionally met with in July and August, but not in sufficient 
numbers to warrant the opinion that it is double-brooded. It 
may be obtained freely by beating. The larva feeds on the 
sallow in the autumn. 
G. minutana, Hub. — A local species, but not uncommon 
where it occurs. The imago appears in July among black 
poplars (Populus nigra), and should be looked for in windy 
weather at rest on the trunks of the trees or on the sheltered 
side of any adjacent palings. The larve are tobe found in May 
and June, feeding on the buds and young leaves of the black 
poplar, and preferring large trees. It has been taken at several 
places round London ; Camberwell, Blackheath, and Wandsworth ; 
also at Croydon and Wimbledon. 
G. trimaculana, Don.—A very variable species, and abundant 
everywhere among elm (Ulmus campestris) in June and July. 
The larva is to be found in May feeding in the shoots and rolled- 
up leaves of the elm, and towards the end of the month the pupe 
are to be found in numbers in the same situations. 
G. Penkleriana, W. V.—Like the preceding species, is very 
variable, and also abundant everywhere among alder (Alnus 
glutinosa) and hazel (Corylus avellana) in June and July. The 
imago flies freely at dusk, and may also be readily obtained 
by beating. The larva is said to feed in the catkins of alder in 
March. 
G. obtusana, Haw. — Not uncommon among oak (Quercus 
robur) and hazel. The imago appears towards the middle of 
May, and flies freely about an hour before sunset. It occurs at 
Lewisham, Darenth, near Strood, Tunbridge Wells, and Folke- 
stone ; Croydon, West Wickham, and Haslemere; also sparingly 
at Hastings. 
G. nevana, Hub.—Abundant everywhere among holly (llex 
aquifolium), the imago appearing in August and September, 
while the larva may be found in plenty feeding in the young 
shoots in May and June. 
G. geminana, Steph. — A local species, occurring. among
